Specification of Letters Patent.

Application filed June 8, .1917.

To all whom it may concern: 1

Be it known that I, WILLIAM R. NIooLL,

Jr., a citizen of the United States, residingv of parts for effectively and efficiently accomplishing the desired result.

In the accompanying'drawings, Figure 1 is a side elevation of a device constructed in accordance with the principles of my invention; Fig. 1 is a fragmentary view showing-one of the doors open and one closed; Fig. 2 is a view of the drivingend; Fig. 3 is a sectional detail of the driving end construction taken on the line 3-3 of Fig. 2, and Fig. 4. is a sectional view of an injector.

In order to produce'a uniform grade of butter which doesnot vary in quality from day to day, it is found necessary to have absolute control of the ripening of cream by first heating it to a pasteurizing temperature uniformlythroughout and then allowing the cream to cool and ripen in the regu-v lar way. The present invention is for the purpose of accurately controlling and regu 'lating the temperature of cream in the making of butter, although, of course, it may have a more general application to the heating and cooling of any liquid.

In the present invention, a vat 1 is mounted on spaced supports 2 each in the form of a saddle with two legs to which the vat is secured with perforated brackets 3 extending from the sides of each support to carry'a circulating pipe 4 on one side and a stubpipe 5 on the other, the pipes acting as spacers for holding the supports in place. At the top of the vat are -two doors 6 hinged about the longitudinal center and supported by brackets 7 at the ends which extend a substantial distance above the doors with connecting arms secured to the doors so that when either one is raised, as shown in, Fig. 1, there is a considerable distance Patented Nov. 19, 1918..

between the door and the top of the ripening coil 9 within the vat. This is for the purpose of making the coil easy of access for cleaning. At the ends of the vat are pivoted arms 10 with notches 11 at the ends which are adapted to engage projecting pins 12 extending from the doors 6, so that the doors may be held in a number of open positions. At the edges of the vat are a number of clamps 13 for engaging the edges of the doors and holding them in position.

The walls of the vat are made up with a body 14 of wood which is covered on the outside with sheet metal 15. On the inside of the body 14 is a layer 16 of insulating material, preferably oftwo thicknesses, and covering the insulating material is a sheet 17 of water-proof paper. On the inside is a metal lining 18 preferably of copper which is tinned or coated on the inside and preferably at the seams making a sanitary and easily cleaned construction. The waterproof paper 17 is interposed between the metal lining and theinsulation 16 to prevent any moisture getting to the insulation that might result from the changing of temperatures, causing the lining to sweat.

. Attached to each end of the vat is a plate 19 having a packing box 20 of suflicient length to extend throughjthe wall of the vat, and threaded at the inner end for the reception of a collar 21 which is screwed tightly against the inside metal lining 18 of the vat thereby making a fluid tight and sanitary joint. The ripening coil 9, within the vat, is madein'the form of a spiral to each end of which is attached a T 22 with a partition23 cast in one of the opposite openings instead'of using a wooden plug, as has previously been the practice in constructions of this kind. Connecting the Ts 22 at the ends of the coil is a pipe 24 which is therefore closed at theends by the partitions 23 so that no fluid is allowed to flow directly between the Ts. This pipe 24 spaces the Ts apart and the entire coil 9 may therefore be placed in-or removed from the vat when the end supports are disengaged.

In order to support the coil 9 within the vat, a pipe 25, threaded at the inner end, is inserted through the packing box20 and threaded into the end of the T 22. A packing gland 26 and packing 27 make a tight thepipe between bracket 29 and the. plate l9, and meshing with this gear is a driving pinion 33 mounted on a shaft/34 which carries pulleys 35, one being loose and the other fast on the shaft. Extending" upwardly from the bearing 28 is a pipe 36 with a faucet 37 at the upper end, and connected" to the outer end of the bearing is a pipe 38 which is connected througha check valve 39 and short pipes 40 with the circulating pipe 4 at 'theside of the vat. The pipe36 admits air to' the coil forcontrolling the amount of circulating fluid passing in the pump or self-circulating means.

Atthe other end of' the vat is a tank 41 ings 44' surroundingthe'nozzle 43 for the admission ofliquid from'within'the tank 7 '41. The nozzle 43 is connected, by means of a pipe 45,"to a suitable source of steam pressure or 'cold water" supply, neither of pipe connection 46 which discharges into" the top of tank '41 thereby permitting the liquid inthe tank to be reused' Extending from the top of 'the tank is an overflow" chance for leakage and infact a minimum" number of packlng oints are needed, so that which are shown or described. Connected to the bearing 28 at this end of the vat is a pipe 47.

ing," but also because there is very little 'there' is less opportunity for leakage. The

"placed in the vat and if thetempera ture is "en'tire coil 9 is easily removable from within the vat by simply loosening the brackets 29 and unscrewing the pipes 25, which consti- 1tute both the bearings and the supports for the coil, from their engagement with the Ts 22. In operation, the liquidto be'tempered is to be raised or lowered, a heating or cooling liquid is forced throughfthe'spira1 coil 9,

the coil being rotated at the same "time by means"of'the" driving pulley so that the liquid in the vat will'be uniformly tem pered, not only by the movement of the liquid itself, but by the circulation of the tempering 'fiuid'in the coil. "The rotation of" the pressure causes it to act as a pumpor a selfcirculating means; when pressure 1s applied to the pipe 4 for forcing liquidv throughthe coil 9, the valve or faucet 37 is closed, but

' the coil, a plate secured "to the end-of the vat having a"packing"bo i"through which the 'tubularmember extends, acking and a packing gland for making a flied-tight connection with' the saidbox, and a bearingfor the outer end' of 'eacli 'tubular member, a bracket securable' to the end "of the "vat 11ming a bearing'poiftioh at a'distance fromthe end of the vatinto' which 'the'end" ofthe tubular member extends, andi paclring means surrounding the outer end of the 'tubul'ar'niember'and' in"c'on"u'ncti'on with the bearing portion of the bracket for making a fluid ti'ght' connection therewith.-

3. In ari'pener'and pa'steurizer, the com- The construction "shown is sanitary not only because the interior of the vat andall of the parts are easily accessible for clean-' bination with a vat, of a coil rotatable therein', a T member for eachend"of"the coil, 'means for holding the Ts at aspaced "distance apart, and a tubular member extending through each end of the vat and threaded into the T" for forming connection with i the coil.

In testimony whereof I have signed my name to this specification, on this 31st day of May, A. D. 1917.
